2.0μm 1940nm Single Mode CW Fiber Lasers for Plastic Laser Welding
2.0μm 1940nm Single Mode CW Fiber Lasers for Plastic Laser Welding
Techwin 2.0μm CW fiber lasers are eye-safe high power fiber lasers. These fiber lasers employ integrated design of all fiber structure and use double cladding fiber pumping technology, thus realizing high performance output laser. The output power can be up to 100W and near diffraction-limited beam quality is achieved at the same time. They can be widely used in the areas of scientific research, experimental teaching and device testing.
Techwin 2.0μm CW fiber lasers employ the control system based on microprocessor which has stable property, long lifetime and free maintenance. With a clear interface and easy control, the LCD on the front panel can give a real-time display of the operating state of the output power and temperature. The LCD can also offer warning messages. Besides, in order to be convenient for system integration, our company can offer modularized fiber laser encapsulation according to the user`s requirements.
